Subject: [PATCH] Update __main__.py
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New CLI helpers

    Added support for:

    script/run --list-input-devices
    script/run --list-output-devices

    These code paths:

        Initialize just enough of the audio stack to enumerate devices.

        Print a clean, human-readable list of input/output devices (including PipeWire / PulseAudio virtual devices like Echo-Cancel Source and pipewire/echo-cancel-sink).

        Exit cleanly with status 0 instead of trying to start the full LVA process afterward (fixing the previous CalledProcessError when --list-output-devices was used).

Behavior change

    __main__.py now treats the “list devices” modes as early-exit utility modes, not “run LVA and then also print devices”.

    This makes it practical to use these commands in setup docs and shell scripts.
